Question

Which two systems work together to make sure that all your cells get oxygen and get rid of carbon dioxide?

circulatory and respiratory
circulatory and digestive
muscular and skeletal
muscular and respiratory

Answer 1

For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide.
